MicroLite Solution – Monitoring Cherries Stored in Controlled Atmosphere Containers


Fruitlab Research and Development Company and Application Cooling Fruit SCC Ltd., successfully stored cherries in controlled atmosphere containers from Janny MT France  for a period of up to 25 days. In order to verify the actual preservation ability of these cherries in these specialized containers, compared to regular commercial storage methods, the company decided to conduct a controlled experiment.

This method of prolonging the shelf life of agricultural products is an excellent solution for growers with medium volumes of fruits (1 to 100  tons), for whom it’s not economical to utilize a full-size controlled atmosphere cooling room.

Additional experiments have been performed with a variety of fruit and vegetables including cabbages, pears, lychees,  pomegranates and various organic fruits, which are grown in small volumes.

Background:

Fruitlab Research and Development Company and Application Cooling Fruit SCC Ltd., successfully stored cherries in controlled atmosphere containers from Janny MT France  for a period of up to 25 days. In order to verify the actual preservation ability of these cherries in these specialized containers, compared to regular commercial storage methods, the company decided to conduct a controlled experiment.

This method of prolonging the shelf life of agricultural products is an excellent solution for growers with medium volumes of fruits (1 to 100  tons), for whom it’s not economical to utilize a full-size controlled atmosphere cooling room.

Additional experiments have been performed with a variety of fruit and vegetables including cabbages, pears, lychees,  pomegranates and various organic fruits, which are grown in small volumes.


Materials and Method:

Cherries of two different varieties underwent a commercial hydro-cooling process and stored in a refrigerator until they were entered into the test containers. Cherries packed in the regular commercial method were used as the control group. During the experiment the oxygen and carbon dioxide levels were monitored twice a day - both levels should be around 5% in order to delay the ripening of the cherries. The containers were kept in a refrigerated room with the  temperature set between 0 to 2 °C. The cherries were examined before they were entered into the containers as well as at the end of the experiment, to check the influence on their taste and condition.


MicroLite Implementation:

The MicroLite II Temperature USB data logger was used inside the controlled atmosphere  containers  and inside the refrigerated room in order to monitor the temperature and to verify that the required temperature conditions (0 to 2° C) were kept. The MicroLite data logger monitored and recorded the temperature and provided comprehensive data analysis with the complimentary DataSuite software.


Experiment Results

  • Storing the cherries inside the controlled atmosphere containers in collaboration with the gas control mechanism monitored by the MicroLite device, enabled a savings of 1.2% of agricultural produce (a distinct reduction in the cherries’ weight loss) in three weeks.
  • The combination of the controlled atmosphere containers with the MicroLite device can provide medium growers and packing houses with the opprotunity to control fruit that have been preserved for a longer time.
  • An extension of the experiment by two more weeks would have probably shown that the quality of the cherries kept inside the controlled atmosphere containers was better than the quality of the cherries kept in the regular commercial conditions.
